z/OS LOGON RECONNECT Recovery.
Paul Gilmartin
leaving an ISPF session inconspicuously minimized in the dock
and goes home. Since it's z/OS 1.11, he can LOGON RECONNECT
and usurp the TSO session and proceed. But his home terminal
emulator doesn't provide the screen geometry he was using in
the office, and he gets an endless recurrence of:
** ISPF screen input error - code = 25 **
***
as he presses ENTER repeatedly. How can he terminate this and
get a useful TSO session? CANCEL would be OK; Edit Recovery
should rescue his work.
If he reconnects to a session left at the TSO READY prompt, all
is well: he can relaunch ISPF which starts with the new screen
geometry. But if he reconnects with ISPF active, either TSO
fails to inform ISPF of the change or ISPF fails to ask.
Given the z/OS improved RECONNECT capability, recovery from
repeated screen errors should include reloading the terminal
characteristics in case anything has changed. As a point of
reference, VM/CMS XEDIT handles this scenario seamlessly:
the user just presses PA2 and the screen is redrawn according
to the new geometry.

Is this not the exact case for which the RESHOW key was designed?

consistent screen dimensions?
My site uses a TSO logon pre-prompt exit. That is, we have our own logon
screen. I am not sure of the mechanism, but it 'knows' that you are
already logged on and also knows that the screen size is different and you
have a choice of reconnect or new session. When 'new session' is
selected, the exit issues a cancel command before actually logging on.
Sorry, I do not have the source and cannot share. But I mention it to say
that it is possible.

Is PA2 RESHOW? PA2 gives me a one-pixel dot in the upper left
corner of the screen, after which pressing any other key puts me
back at "screen input error". The implementation appears to fall
woefully short of the design. Given that RECONNECT is now
possible, RESHOW ought to first refetch the terminal attributes.

Gil,
If the user presses PA1, or ATTN, eventually they should get to a READY or
LOGON prompt. If that doesn't work, the only option would be to call the
operator for a C U= command. This is a VTAM thing as much as a TSO thing.
I don't believe that VTAM supports dynamically modifying screen sizes of an
active session.

I missed the part about this being different screen sizes. My bad. :-|
VTAM absolutely *does* support changing screen sizes on the fly. It's
called "re-bind". You can re-bind as long as you're in between brackets.
We do it in some of our more sophisticated products that use 3270
interfaces.
I'm not sure if TSO/E ever uses the re-bind feature. But, even if it
does, it would be unlikely to re-bind while a command processor is in
control. That could create some serious confusion for the command
processor. In particular, I'm certain ISPF would "choke" on this...

Gasp!
Long ago, Bill Schoen posted a wrapper to the MVS-OE Tools & Toys
site which invokes the batch SDSF load module. So, I just log on
to Unix System Services, bring up that flavor of SDSF (I've
enhanced it somewhat) ahd cancel my TSO session.
But this is a circumvention. It doesn't justify the fundamental
defect in ISPF.

I see you manually submitted the PC file to JES to run as a job.
fwiw, you could put the FTP commands in a file and submit it as input
to the FTP command using the -s: parm: FTP -S:filename
I have an application that lets me enter "SUB" in my KEDIT command
line (while I'm editing MVS or VSE JCL) similar to the SUB command in
ISPF/PDF. I've wondered if there is a commercial opportunity for it.
It also allows me to code the same variables in JCL as in SYSIN data.
Something like this:
%PARMS %USER=WRL3
//CANCEL JOB CLASS=B,MSGCLASS=Z
//MVSOUT OUTPUT DEST=WRL1,FORMS=MVS,JESDS=ALL,DEFAULT=YES
//CANCEL EXEC PGM=ISFAFD
//ISFOUT DD SYSOUT=L
//ISFIN DD *
/C U=%USER
//
I use a product of ours called JRB to return the listing to a network
folder, so I don't need PDF or SDSF to submit jobs or view the
listings--I do it all from within the PC editor.
Do you (or anyone else) often submit jobs from PC files? Would there
be interest in doing that?
